The items for sale range from food like Pringles and chocolate bars to iPhone charging cords and the box also includes some free snacks for passengers - something that would certainly have its appeal at the end of a big night.

"Everybody wants to tell you they're so healthy but sweet and salty snacks do really, really well," Mr Cripe said.

Currently Cargo only has drivers operating in major American cities but has big plans to expand and has already signed up drivers in 50 US states.

"We'll have twice as many stores in North America as 7-Eleven," he said.

As if you could help yourself on a late night ride home.

Cargo supplies ridesharing drivers with the in-car payment system and the box of products for free, as well as delivering free top-ups when items are running low.

Drivers get a 25 per cent commission on all retail sales plus $1 of every order - even if the passenger takes one of the freebie snacks.

It's certainly a clever way for an outside company to capitalise on the growth of the ridesharing industry, not to mention the value of collecting data on drivers and passengers, as well as the time and location certain products are sold.

Cargo markets itself to drivers as a way for them to earn extra money while on the road as well as a way to give their passengers a "5-star" experience, a reference to the rating system used by Uber passengers to rate their driver.

According to the company, the average driver earns about $100 to $115 per month by selling the snacks and other items.

It might take some time for a similar thing to take off in Australia but I for one would welcome the chance to buy skittles on the car ride home.
